Plumb linklayer channel stats from HAL

Go through the list of channel stats present in WiFiLinkLayerStats-radio
stats and copy onTimeInMs and ccaBusyTimeInMs to framework.

Bug: 79111545
Test: Unit Test
Test: Verified the stats by printing out WiFiLinkLayerStats.toString() manually
Test: ./wifi/tests/wifitests/runtests.sh
